Package synthesis
Module qimager
Tool qimager


Set some general options for subsequent processing


Synopsis
setoptions(ftmachine, cache, tile, gridfunction, padding)


Description
Various less-often-used options for processing can be set.

ftmachine
The options for ftmachine are:
wproject
W projection algorithm.
mosaic
Mosaic gridding.
cache
The size of the cache used (in complex pixels) during the gridding process. The default is to use half the physical memory of the machine as specified by the aipsrc variable system.resources.memory.
tile
The side of the tile (in complex pixels) during the gridding process. are supported.
